TBH I hate these thanks, they clutter up the page and IMO are kinda worthless. I know myself and many others couldnt care less about post count/ thanks count. The only thing that counts is how much beaver you have here.
Gav if you do go with it anyway to make it a profile option? So have it show as default profile but allow the thanks Message to be turned off if a user wanted.
IDK if you can do this with the plugin.
